- Comment on Cloudflare built an oauth provider with Claude 2 hours ago:
Dieselgate wasn’t a “bug” it was an designed in feature to circumvent emissions. Claude absolutely would have done the same, since it’s exactly what the designers would have asked it for. Somehow I doubt it would have gone undetected as long if Claude wrote it tho, it’d probably mess it up some other way.

Well, Kioxia sells a 30TB 2.5in SSD right now for about $5k. I’m sure they could make a 60+TB SSD by just stacking 2 of them in a 3.5in case.
- Comment on New fuel cell could enable electric aviation 1 day ago:
From what the article says, this fuel cell produces sodium oxide by reacting sodium with oxygen. There’s no hydrogen gas being produced in the fuel cell.
The emissions are sodium hydroxide, or sodium carbonate after it reacts with carbon in the air.
(Also now I’m not sure where I got 1200Wh/kg from. The article says both 1000 and 1500 Wh/kg)
- Comment on New fuel cell could enable electric aviation 2 days ago:
They’re comparing it to lithium batteries for power density, but ignoring that the sodium metal in this case is a consumable, unlike batteries.
They say it’s 1200 Wh / kg of sodium, however gasoline is a whole 3800 Wh / kg, and somehow I think the carbon dioxide is less harmful than the same amount of sodium hydroxide. Not to mention how much more complicated storing liquid sodium would be since it reacts with air.
- Comment on Self-Driving Tesla Fails School Bus Test, Hitting Child-Size Dummies… Meanwhile, Robo-Taxis Hit the Road in 2 Weeks. 5 days ago:
It would be make/model dependent
I’m specially talking about Tesla’s FSD/Autopilot.
While getting a demo of FSD from a friend, their Model 3 correctly stopped at a red light, and 30 seconds later a car ran right through it in the next lane over. That’s how low the bar is for “worst human driver”. Tbh, that human shouldn’t have been on the road if they’re driving past stopped cars through a red light. - Comment on Self-Driving Tesla Fails School Bus Test, Hitting Child-Size Dummies… Meanwhile, Robo-Taxis Hit the Road in 2 Weeks. 5 days ago:
The problem is, it’s already better than the worst human drivers, it’s just that that’s too low a bar. It’s a looong way away from being better than the best human drivers (think taxi and bus drivers who do it every day, or police who actually go through extra vehicle handling training)

There’s plenty of evidence of other people with the same v13.2.8 version before their crash on Feb 27, for example:
- Comment on Can Tesla's Self-Driving Software Handle Bus-Only Lanes? Not Reliably, No. 1 week ago:
Well now you’ve made me go read all their Reddit comments. It happened February 27, and they said it took 2 months for their insurance to get processed. It doesn’t seem unreasonable to me to wait until they’ve got everything sorted out before posting.
Based on pictures of the dash cam files they posted, I don’t think they have internal video, they would have had to turn it on before hand I think? Tesla mostly talks about sentry mode internal camera, so I don’t actually know if it would record by default. But again, I don’t think it’s reasonable to expect them to edit a video with face blurring and everything, they don’t owe the Internet anything, and not everyone even knows how.
- Comment on Can Tesla's Self-Driving Software Handle Bus-Only Lanes? Not Reliably, No. 1 week ago:
Where are you getting February from? As far as I know this happened last week. I don’t blame the person not wanting to reveal their face.
- Comment on Can Tesla's Self-Driving Software Handle Bus-Only Lanes? Not Reliably, No. 1 week ago:
Did you watch the video? There’s no way that it was just “user error”, nobody randomly swerves into a tree when nothing’s there. Maybe you’re implying it was insurance fraud?
Tesla gives out beta access to users, so I wouldn’t put too much weight on that claimed version they were using.

- Comment on Black Mirror AI 1 week ago:
Anything that’s per-commit is part of the “build” in my opinion.
But if you’re running a language server and have stuff like format-on-save enabled, it’s going to use a lot more power as you’re coding.
But like you said, text editing is a small part of the workflow, and looking up docs and browsing code should barely require any CPU, a phone can do it with fractions of a Watt, and a PC should be underclocking when the CPU is underused.
- Comment on Black Mirror AI 1 week ago:
It sounds like it does save you a lot of time then. I haven’t had the same experience, but I did all my learning to program before LLMs.
Personally I think the amount of power saved here is negligible, but it would actually be an interesting study to see just how much it is.
- Comment on Black Mirror AI 1 week ago:
I didn’t even say which direction it was misleading, it’s just not really a valid comparison to compare a single invocation of an LLM with a continuous task.
You’re comparing Volume of Water with Flow Rate. Or if this was power, you’d be comparing Energy (Joules or kWh) with Power (Watts)
- Comment on Black Mirror AI 1 week ago:
Just writing code uses almost no energy. Your PC should be clocking down when you’re not doing anything. 1GHz is plenty for text editing.

I’m pretty sure Tesla has offered delivery to a home pretty much from the very beginning. I remember they had some money back guarantee when they announced it because obviously you can’t test drive if you don’t go to a dealership.

- Comment on Are Future Chips Doomed to Overheat? 1 month ago:
Yeah… chip designers have been battling heat output since silicon doping was invented. The main source of heat is transistors change state, since it doesn’t happen instantly and will disipate more heat when half-on, acting almost like a resistor.
The higher the clock speed, the more time a transistor spends half-on. This is why things like undervolting and underclocking reduce power usage.
Physically smaller transistors usually also means it takes less electrons to saturate the gate, so it allows lower voltages and currents to be used, while still toggling the state at the same speed. (Not to mention timing gets easier the closer the transistors are to each other) - Comment on World's fastest Flash memory developed: writes in just 400 picoseconds 1 month ago:
1 bit / 400 picoseconds is 2.5Gbit/s, or 10x slower than a 1-bit GDDR7 bus.
- Comment on China scientists develop flash memory 10,000× faster than current tech 1 month ago:
That’s pretty much my understanding. Most of the advancements happened in memory speeds are related to the physical proximity of the memory and more efficient transmission/decoding.
GDDR7 chips for example are packed as close as physically possible to the GPU die, and have insane read speeds of 28 Gbps/pin (and a 5090 has a 512-bit bus). Most of the limitation is the connection between GPU and RAM, so speeding up the chips internally 1000x won’t have a noticeable impact without also improving the memory bus.

- Comment on LG TVs’ integrated ads get more personal with tech that analyzes viewer emotions 1 month ago:
I’ve seen this linked before, and unfortunately the specs are very mediocre on their TVs. I don’t know how they can claim a TV is HDR when it has a meh contrast ratio, no dimming zones, and can’t even do 100% of the sRGB color space.
I don’t know how much of the price of other TVs are subsidized by ads, but these Sceptre TVs are pretty bad value when looking at panel specs alone.
- Comment on LG TVs’ integrated ads get more personal with tech that analyzes viewer emotions 1 month ago:
Chances are they’ll have some antenna line going to the edge of the TV. The box on the back of the TV already has a bunch of shielding over it inside. If you were to go to the trouble of opening the TV to find it, you may as well disconnect the antenna and ground it so there’s no chance of a signal.
- Comment on CVE Board members launch the CVE Foundation, a dedicated, non-profit to continue identifying vulnerabilities, after the US ended its contract with Mitre 1 month ago:
The US specifically does spend tax money on foreign aid (or at least they used to). I have no problem with that. If you’re struggling to get by, then you should be paying effectively no taxes. If that’s not the case, then we should be fixing that, not cutting funding to things that make the world better.
- Comment on CVE Board members launch the CVE Foundation, a dedicated, non-profit to continue identifying vulnerabilities, after the US ended its contract with Mitre 1 month ago:
If it has value to a larger community, the larger community should be able to fund its operation.
Up until very recently it seemed perfectly reasonable to fund this sort of thing with taxes, because it benefits everyone even if they’re not directly using the database. An open source developer probably isn’t going to pay to look up vulnerabilities in the open source dependencies they use, so the database being free makes software more secure on average.
What is wrong with having free public services? If someone is abusing it, block them, or charge fees like a library.
- Comment on Elon Musk and Taylor Swift can now hide details of their private jets/// Private aircraft owners can now ask the FAA to keep their registration information out of the public eye. 2 months ago:
What the “middle class” can afford has changed quite a bit in the last few decades. Owning a home is arguably “upper class” at this point. The median US income was only $80k in 2023. Pentions are also getting increasingly rare. What used to be considered middle class is now struggling to get by. Middle class is defined by the income of the middle third of the population, not by a particular lifestyle.
